Along with purchasing heating and lighting systems for your pet tortoise, they’ll also need a substrate – i.e. material for the tortoise to live, play, and burrow in. Now, there’s one important thing to know about tortoise substrates – some are perfectly suited to tortoises and will enable them to live long and happy lives, but please note that some cheaper brands CAN BE DANGEROUS, even potentially lethal should they contain components that disagree with the tortoises digestive system.

So to help you avoid purchasing bad products for your tortoise, we will help you with a few guidelines that you can follow for the sake of your pet’s health. And aside from the guidelines, we will also provide you with a list of the best substrate products for your pet.

Common to Less Common Substrates for Tortoises

There are a lot of substrates that you can choose from when you are about to make a purchase, and when you ask which substrate works best for your pet tortoise, these would be the types of substrates that reptile or amphibian owners will recommend you with.

Here are the most common recommendations from experienced reptile and amphibian owners:

  • Coconut Fiber
  • Aspen Shavings
  • Mosses
  • Organic Mulches
  • Organic Topsoil

The less commonly recommended products are:

  • Reptile Carpets
  • Hemp
  • Recycled or Shredded Newspapers
  • Hay

And these are the types of substrates that you should avoid using for your pet tortoise:

Some of these products can cause impaction to your tortoise’s stomach. However, there are a few exceptions. You can still use some of the products if you have mixed it with other substrates like coconut coir, or if the substrates are packed into large chips, which can be too big for your pet to be swallowed.

If you are planning to mix-in substrates, you can try a mixture of 1/3 of calci-sand and 2/3 of coco fiber of coconut coir. Using bare sand can cause health issues to your tortoise, but you can prevent that from happening if you have mixed in another type of substrate like the coconut fiber.

Some tortoise owners will highly recommend you with reptile carpets as a substrate as it can be used multiple times. If you are considering using a carpet, then make sure that it has no loose fibers that can disable your pet’s movements.

Choosing the Best Tortoise Substrate

If you are planning to keep your tortoise indoors, then you should also consider adding in a substrate when setting up your pet’s terrarium. Aside from heaters, lighting systems, decoration, and other kinds of accessories, having a substrate is also essential to provide the best comfort for your pet.

When placing the substrate in your pet’s terrarium the substrate should be able to fully cover the floor, and the substrate should at least half an inch thick or more. You’ll also need to have a proper composition to ensure your pet’s safety and its health.

Also, whether you are planning to keep your pet indoors or outdoors, you should make sure that their terrarium is not overly moist. Overly moisturized terrarium will make your tortoise prone to infection if they have wounds, or if their skin is unhealed from shedding. Choosing a good substrate will depend on the kind of species your tortoise is.

Here are other things that you should consider before purchasing a substrate:

– If you are currently taking care of a baby tortoise, it would be okay if its terrarium is a bit moisturized than normal, in fact, baby tortoises should be soaked in water for at least three times a day. Baby tortoises needs to be fully hydrated, once they are properly soaked they’ll immediately drink some of the water that they are soaked in.

– If you are taking care of a tortoise that needs mid to high levels of humidity, then you should choose a substrate that can hold moisture well. Look for a substrate that contains sphagnum moss, coconut coir, or peat moss. Other kinds of substrates will also work well, just avoid using sand, pine shavings, and cedar ships as they are toxic when heated, while the sand type can cause impaction on your pet.

– If your pet requires a dry climate, then you can provide it with a substrate that includes dry clippings, or coconut coir.

– I have mentioned earlier about the use of sand. Avoid using that kind of substrate for your pet as it might eat it accidentally, which can bring harm to its health. However, there are sand type substrates that can be ingested by reptiles without causing implications. If you are set on using sand as your pet’s substrate, then consider getting digestible sand for your pet.

– If you are planning on keeping your pet outdoors, then the substrate wouldn’t matter much. The natural environment of the outdoors is enough for your pet’s comfort. If you want to add stimulation for your pet, you can try adding in some peat moss to the outdoor’s environment. Just make sure that the kind of substrate that you want to add in is free of chemicals, and the environment is free of pesticide.
